Per Johan Axel Åhlin (born 7 August 1931) is a Swedish artist and director of animated films. He is known for his collaborations with the comedy duo Hasse & Tage, and for his own projects such as the feature film The Journey to Melonia.

Although eventually best known for his work on children's film, Åhlin was always more interested in films for adult audiences. He has commented on the difficulties of making animated films with adult themes: "I don't know whether the problem lies in the audience or the marketing. But think like this: if you draw like Picasso, Doré or Sergel, then those are images that have no connection to film. If they then would be animated and suddenly started to move - would they become children's film then? I can't understand this!"[3]

Åhlin has developed several films which have never been finished due to lack of funding or interested producers. His personal dream project, which has been in development since 1992, is the feature film Hoffmanns ögon ("Hoffmann's eyes"), which is based on Jacques Offenbach's opera The Tales of Hoffmann. As of 2009, Åhlin said that he still occasionally works on the project on his own: "Hopefully it can become a few minutes which can give potential producers remorse in the future".[4][5] Other unfinished films include Den magiska saxofonen ("The magic saxophone"), HC Andersen, and an adaptation of Eric Linklater's The Wind on the Moon, with a screenplay by Ulf Stark. Designs and other finished material from these projects have been exhibited multiple times at events in Sweden.[5][6]
